UNITED STATESA CARL GOHLIN, OF

NEW YORK, N. Y.

ELECTRICAL HEATlNe APPARATUS.

SPECIFICATION forming part of Letters rei-.ent No. 664,081, dated December 18, 1900.

Application led July 26, 1900.

To all whom it may concern:

` Be it known that I, CARL GOHLIN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Electrical Heating Apparatus, of which the following is a full and complete specication, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to electrical heating apparatus for use in the treatment of rheumatism, nerve troubles, and other afictions by what is known as the hot-air process, and the object of the invention is to provide an apparatus of this class which is simple in construction and operation and which is designed for use in connection with a bed, cot, table, or other support on which the patient is placed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of myimprovement are designated by the same reference characters in each of the views, and in which- Figure 1 is a side view of my improved apparatus, showing also a table, cot, or other support; Fig. 2, an end view thereof; Fig. 3, a partial transverse section of one side of the apparatus on the line 3 3 of Fig. 1, the table or other support being not shown; Fig. 11, a plan yiew of a detail of the construction, and Fig. 5 a sectional view similar to that shown in Fig. 3 and showing a detail of the construction.

In the drawings forming part of this specitication I have shown at 6 a table, cot, orf

other support; but in the practice of my invention an ordinary bed may be substituted for said table, cot, or other support, and in the practice of my invention I provide an apparatus of the class and for the purpose specified which comprises two similar oblong rectangular frames or casings 7, said frames or casings being each segmental in cross-section and each representing in crosssection approximately a quarter of a circle. The frames or casings 7 are composed of top and bottom bars 8, shown in Fig. 3, and end bars 10, shown in dotted lines in Fig. 1, and two of which are shown in full lines in Fig.

Serial No. 24,861. (No model.)

2, and with which are connected an outer shell 11 composed of metal, and an inner shell 12, which forms a reiiector, and the outer and inner shells 11 and 12 are both segmental in cross-section and between the saine is a space or chamber 13, similar in form to the frames or casings 7 and occupying the entire area between the top and bottom bars 8, end bars 10, the outer shell 11, and the inner shell or reflector 12.

Secured to the inner shell or reflector 12 of each of the frames or casings 7 are a plurality of incandescent lights 111, any desired number of which may be employed and some of which are shown in full lines in Figs. 1, 2, 3, and 11 and part of which are shown in dotted lines in Figs. 1 and 2. These incandescent lights are of the ordinary form and construction and are so connected with the inner shell or reiiector 12 of the frames or casings 7 that they are held in a horizontal position closely adjacent thereto, the connection of the lights with the inner shell or retlector 12 being made by means of elbowcouplings 15, which pass outwardly through the inner shell and which terminate within the space 13, between -t-he outer and inner shells 11 and 12 of said frames or casings.

Each of the frames or casings 7 is provided, preferably at one end, with an opening 16, through which electric wires or conductors 17 and 18 are passed, and these wires or conductors are passed through the space or chamber 13 in any desired manner and each of the electric lights 14 is connected therewith. For the purposes of this description the wire 17 will be called the positive wire and the wire 18 the negative wire, and each electric light is lconnected with the positive wire 17 by a wire 19 and with the negative wire 18 by another wire 20, and each light is also provided with a switch device 21, which passes through the outer shell 11 and operates in connection with the wire 19. As thus constructed it will be seen that when the circuit is closed through the wires 17 and 18 all of theelectric lights in each frame or casing will be actuated, and it will also be apparent that either one or any number of said lights may be cut oft or the current thereto cut oit by` operating the corresponding switch 21.

Each of the frames or casings7 is supported IOO at its opposite ends by standards 22, which are provided with spider-feet 24, each arm of which is provided with a roller 25, whereby the said frames or casings may be moved from point to point whenever desired, andthe connection between said frames or casings and the standards 22 is made by means of sfglnental brackets 2G, secured to the opposite ends of said casing, and arms 27, provided with tubular heads 28, through which the standards 22 pass and which are adjustable on said standards, and the arms 27 are provided with angular extensions 29, which pass throughthe segmental brackets 26 and on which the frames or casings 7 are adapted to turn7 this construction being .clearly shown in Figs. l, 2, and L The arms 27 are adjustable on the standards 22 by means of setscrews 30, which pass through the heads 2S, and it will thus be seen that the separate frames or casings 7 are vertically adjustable on the standards 22 and may be turned into any desired position on the arms 27, the last movement being in a vertical plane. Each of the frames or casings 7 is also provided at each end with knobs or buttons 3l, any desired number of which may be employed, and in order to close the ends of said frames or casings when in use I provide hoods 32, coniposed of textile material, one of which is shown in Fig. 2, and these hoods are buttoned onto the knobs or buttons 3l. Said hoods may be of any desired dimensions, the object thereof being to practically close the space at the ends of the frames or casings and between the same and the table, cot, or bed G.

In the use of the apparatus, as hereinafter described, the table, bed, or cot 6 is longer than the frames or casings 7, and in practice the said frames or casings are connected therewith, so that one end thereof projects, as shown in Fig. l, the object of this arrangement being to provide means whereby the head and shoulders of the patient, if the latter is desired, will project from the space inclosed by the frames or casings 7 and-the hoods 32 at the ends thereof.

In practice the patient is placed on the table, cot, or bed 6 and the frames or casings 7 are moved up into position, as shown in Figs. l and 2, and in this position the said frames or casings, together with the table, cot, or bed and the hoods 32 at the ends of the frames or casings, form a closed space in which the entire body of the patient rests. In this operation the hoods 32 may be so adjusted as to cover the shoulders of the patient and cover everything except the head, which must be left uncovered. When the parts of the apparatus are thus adjusted and the patient is in position therein, the current is established through the wires 17 and 18 and the electric lights 14 are actuated and the light and heat rays therefrom are reflected from the inner shell or reflector 12 of the frames or casings onto the body of the patient. The heat thus generated is great and any desired degree of heat may be obtained, and the results produced are similar to the results produced in other and well-known apparatus of this class now in use.

The apparatus herein described is simple in construction and operation and comparatively inexpensive and may be used in connection with an ordinary table, cot, or bed, as hereinbefore described, or a suitable support for the patient may be provided, and for this purpose an ordinary table, such as that shown in the drawings, provided with a mattress, may be employed,
